UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, O.C. 20555-0001 December 16, 2019 Mr. James Barstow Vice President, Nuclear Regulatory Affairs and Support Services Tennessee Valley Authority 1101 Market Street, LP 4A-C Chattanooga, TN 37402-2801

SUBJECT:

WATIS BAR NUCLEAR PLANT, UNITS 1 AND 2 - CORRECTION OF ERRORS ASSOCIATED WITH AMENDMENT NOS. 129 AND 32 REGARDING CHANGES TO TECHNICAL SPECIFICATIONS 3.8.1, 3.8.7, 3.8.8, AND 3.8.9 (EPID L-2018-LLA-0492)

Dear Mr. Barstow:

By letter dated November 26, 2019 (Agencywide Documents Access and Management System Accession No. ML19238A005), the U.S. Nuclear Regulatory Commission (NRC or the Commission) issued Amendment Nos. 129 and 32 to Facility Operating License Nos. NPF-90 and NPF-96 for the Watts Bar Nuclear Plant (Watts Bar), Unit 1 and Unit 2, respectively. These amendments were in response to your application dated November 26, 2018, as supplemented by letters dated May 13, 2019, and October 9, 2019.

The amendments revised Watts Bar, Unit 1 and Unit 2, Technical Specification (TS} 3.8.1, "AC [Alternating Current] Sources - Operating"; TS 3.8.7, "Inverters - Operating"; TS 3.8.8, "Inverters - Shutdown"; and TS 3.8.9, "Distribution Systems - Operating," to support performance of the 6.9 kilovolt and 480 volt shutdown boards maintenance.

Subsequent to issuance of the amendments, the NRC staff noticed missing revision bars in revised TS pages 3.8-2b for the "(continued)" word that was added in the ACTIONS heading.

Also, in the Attachment pages, a "---" should have appeared in the Remove Pages column for new page 3.8-42a for Unit 1, and a "---" should have appeared in the Remove Pages column for new pages 3.8-4a and 3.8-38a for Unit 2.

In addition, the licensee notified the NRC of an error in page 3 of the Watts Bar, Unit 2, license, which was associated with the wording of the existing License Condition 2.C.(4). This license condition should have read as follows:

(4)

PAD4TCD may be used to establish core operating limits until the WBN Unit 2 steam generators are replaced with steam generators equivalent to the existing steam generators at WBN Unit 1 *.

Enclosed are the replacement pages associated with these amendments. The revised Attachment pages and TS pages contain a marginal line indicating the area of change. We apologize for any inconvenience caused.
